Doon-FASTENER.

To all whom it may concern:

Be it known that I, SAMUEL Pinon `STE- vENsoN, of Chester, in the countyof Delaware and State of Pennsylvania, have invented certain new anduseful Improvements in Door-Fasteners, whereof the following is aspecification, reference being had tothe ac companying drawings.

adjacent portion of the door.

longitudinal section through the fastener,-

The object of my invention yis to provide a fastener which shall meetthe requirements of such doors as are used u on refrigerating apartmentsand the like, W ere it is necesand adjacent portion of the door, takenon the line II, II, in Fig. I;

In the accompanyin drawings, 1, represents a hollow door of t e ordinaryt e employed in such structures, having a fi ing of nonconductingmaterial, and 2, re resents a aclnng strip of compressible an preferab yelastic material applied laround the margin ofthe door, so as to form aclose joint with the surface ofthe doorway. The baseplate 3, of thefastener is secured to the door by means of screws and is provided with.guides 4, 4, for the sliding bolt. 5, formed of a wide and flat elasticstrip of metal whose front/extremity 6, is curved inwardly. The bolt 5,is attached by a screw in 7, to one end of a link 8, the other endo saidlink be- A ing provided with a hole which engages with a stud 9, upon anovfl plate 10. Said plate 10, has a second stud 11,diametrically-opposite to the stud 9, and the inner ends of said twostuds are secured td'a second oval plate 12, which constitutes the headof a s indle 22, extending through the door. The p ate 10, has a squaredprojection 13, adapted tok receive a lever-handle 14, and the spindle22, is provided with a similar squared end 15, upon the other side ofthe door adapted toeiigage the lever-handle 16.

` L'Ihe bearings for` the spindlje'gare previded in the base plate 3,and the ate 24.,

,secured upon the' opposite side -of t e door.

Intermediate` between these bearing poi-nts vthe spindle 22.,lis'surrounded b r an elongated paclrin 25, of'such abserfent 4characteras is ac apted to be i'naintainedl in a greased condition, felt beingpreferab'lyused for the purpose. This packingis maintained in positionaround the- `spindle by means of a thin sleeve 2.6, which Vis mountedina proper recess formed in the wood work of the door between the plates3, 'and' 24'. The purpose of this packing is to revent the ingress ofmoisture and its conge ationnpon the working parts in such a hardcondition'-v s might impedethe free manipulgtion'of the olt'.

Rests 17, and 18, are secured lupon the opposite sides of the door inthe prio er relationspending with the locking o the bolt. The Y idoorwayvis provided with a hasplg, having. a freely' mounted roller 23,arranged in such relation to the plane of movement of the bolt, that theinwardly curved front end 6, thereof, when projected, shall pass insidebe sprung inwar s, or towards the door-way, thus tendingto press thedoor tightly in its closed position. Rotation of either the handle 14,or the handle 1.6, to the right in vFig. I, will actuate the link 8, andwithdraw the boltfrom contact with the hasp roller, the movement in thisdirection beirrf1r limited by contact between the stud] 1, an the underside of the'link 8, at 'which pointfurther rotat-ion of the oval plates10, and 12, wili be arrested. In this position, the handles will havebeen thrown some distance past the vertical, and hence the devicewillrest in the its engagement therewith,

open v position until intentionally shifted,

Obviously, when the bolt has been shot for closingthe door, the twohandles will be supported in the rests 17, and 18, and; hence be safeagainst an@v other than intentional" displacement.

Ho es 20,.and`21, may be formed in the respective handles and rests,

. so as to permit them vto be secured by means i of a pad-lock.

Having thus clair described niy` invention, I4

1. The combination cfa bolt insa direction transversely' of its length,means fon\shifting 7.1i to receiye lthe handles 14, an 16', when rturned into the extreme ostion, corre- Ytransversely of its length; alink; a rotatable l plate having studs, one of which is connected Withsaid link and the other of which is adapted to engage with the surfaceof said link in one extreme positifn; a spindle for actuating saidplate; a handle for said s indle; and a hasp having a roller adapte( toengage the front end of said bolt.

3. In a securing device for doors of re- I l l frifrerafnfr apartments,the combination,l

with a door; of. a sliding bolt mounted upon the inner face of saiddoor; an actuating spindle for said bolt, which spindle passes entirelythrough the door; an elongated greased packing of absorbent materialsurrounding said spindle; and a sleeve surrounding said packing.

ln witness whereof, I have hereunto signed my name, at Philadelphia, inthe State of Pennsylvania, this eleventh day of April, 1905.
